    Vacation with the V

    We are going to use the V a lot this summer. I use it as a daily driver, even in wintertime but this will be the first vacation use. First I'm going on a trip with my seven year old daughter (wife has to work) to celebrate my father’s 75th birthday. The celebration will be in a northern part of Sweden so I suppose that trip will be about a thousand miles. The second trip will be with my family down to Germany through Denmark (I'm allergic to ferries or rather against dents and scratches from other cars). We are going to the southern part of Germany (Berchtesgaden) and enjoy the scenery, probably visit the "eagles nest" and of course enjoy the V at speed on the autobahn! Hopefully I can convince my wife to ride on a museum small gage railway in a part called Harz. Very steep grades and tight curves on that railroad and they use ten-coupled steam locomotives, the most powerful in Germany with their 700 bhp. Not a Big-Boy with almost 7000 bhp, but a large power for a narrow gauge railway. After that it is probably time for new tires... I hope that you guys are enjoying your vacations!
  2. We recently sold the STS after almost 180k miles in the family (199 k miles on the odometer). It was still running very good, no rust, interior almost as good as new but the age and miles was starting to show. It has the half-case oil leak and small stuff needed attention. The catalytic converter gave up and needed replacement so I replaced it with an aftermarket. But that unit was to small for a 4.6 liter engine so I replaced it once again but this time with an used OEM unit that recently gave up. The new owner has owned a lot of American cars and has also worked as a mechanic on several Cadillacs and therefore had "the right buyer profile". I am convinced it has come to a good new home although he didn't seem to be as picky about cleaning and keeping the exterior/interior in good trim as I am...

    I was speaking of the fuel injection connector. It’s a 2002 year model.

    Hi all! I just returned from a test drive. The Time Sert kit for sparkplugs worked like a charm (I used the extended kit for deep spark plug holes). A couple of hours work to remove all stuff, use the insert kit and put it back together. (I had to put everything back together and move the STS after a found out the threads was stripped because I want my V to be in the garage at nights). No mechanical noises and a perfect idle. One funny thing happened though. I had removed the electrical connector for that cylinder in order to move the car safely while I was waiting for the Time Sert kit to arrive. When I first put everything back together it ran avfully. A dead miss on that cylinder. I removed the connector and gave it a dab of WD40 and excercised the connector by connecting and removing it about ten times to remove oxides. Then it ran as it should. I have seen that before. If you pull a connector that has not been moved in many years then contact is likely to fail. I guess it is because the contact surfaces has bonded over the years and if ever so slightly disturbed you loose contact. To exercise the connector is a good way to get contact.

    Great tip! I've just recently begun using a dentist type of mirror. I guess I'm old school My theory is that I once overtightened that plug with a faulty torque wrench which in turn eventually made the threads fail. I have just ordered a kit from Time-Sert with a couple of inserts. I can't imagine that there are mechanical issues since it ran fine otherwise. No mechanical sounds and no signs of marks from collisions at the top of the piston. Of course carbon build ups could ruin a plug but that engine has been exercised from day one

    I thought about contact too. I tried to see if something was present on the top of the piston but it looked ok. This plug had a bend center electrode and the threads was stripped. Could it be carbon build up damaging the electrode?

    Hi all! Finally the spring has arrived over here. That means summer tires, a thorough cleaning and waxing and a general tune up on the cars! I finished my V so I thought it was time to do my wife’s STS, so I started it up and was heading for the garage but suddenly it started to miss. Pulled the plugs today and found out that the threads were gone at one of the cylinders at the rear bank. If you recall, I had a problem about one year ago when I found a plug at that exact location with a destroyed center electrode. That plug was loose then so I figure that the threads were severely weakened when the plug was rocking back and forth. Ironically I used a torque wrench a couple of years ago (in order to go easy on the threads…haha) to install the last set of plugs and I am quite convinced that the wrench was off which in turn caused the stripped threads. About a year later another plug at the exact location was damaged and loose and the threads are all gone. I’m planning on buying a Time-Sert kit for spark plug repairs that supposedly will work with engine in place. I’ll let you know about my findings.

    I agree. The best protection is to get the car rust proof from the factory but if one likes to drive all year around then this is a well working solution ( http://www.dinol.com). Especially since many cars don’t have a very good protection from the factory to start with. Cadillacs don’t rust as easy as other cars but if they are unprotected they will. First they raise the car on a lift and remove the wheels and the plastic panels under it and wash the car with high pressure. I really don't care for high pressure washes for everyday use since the pressure forces water through seals and under coating materials and is hard on the paint. But since they dry the car for a day at raised temperature afterwards it is ok. Then they use a thin wax-based fluid in cavities, doors, beams and sills which also seals the seams between the sheet metal parts. After that they use a thin wax based fluid in the wheel wells and underneath the whole car followed by a thicker coating to prevent abrasive wear from dirt and stones. Best would be to have two Cadillacs. One for wintertime driving and one for summer driving .

    Head gasket problems are just about the only major problem you will ever have with a Northstar and I would say that it does not happen more often than on any other car. It is extraordinary to be able to enjoy the power, the smoothness, the ride and handling and have that reliability. Wifeys STS still have original water pump, starter, alternator, thermostat, shocks, exhaust system (except from the cat that said good bye at about 160k miles), AC etc. after 16 years and almost 200k miles. I still use it quite regularly to excercise it and it sees 120+ mph almost every time

    I use undercoating on my cars since they use a lot af road salt over here. I have had a 1988 Eldorado, a 1993 STS, a 2002 STS and now a 2012 CTS-V and have used the Tuff-Cote Dinol treatment. Perhaps it is called Dinitrol in US. All of them passed over 150k miles without any signs of rust. Just some bubbles on the paint around the fuel filler neck on wifeys STS after almost 200k miles! So it is possible to enjoy your dream car all year around Obviously some people think I am crazy to use a near 600 hp rear wheel drive car in the winter...

    I once read on a Corvette forum about a guy who had a C6 and a Z06 for everyday driving. Except from in the winter when he drove some Japanese car. He said that it was a good choice since he did not care at all about that car. He could total it and still have a smile on his face. This is why Toyota remains in business

    You´re welcome! I really recommend the FSM. Every car sometimes has an issue. It´s not that a Cadillac breaks down more than other cars. I have my fourth one now and I am really pleased with the reliability! I used to drive Volvos because everybody over here believes that they make the ultimate reliable cars. From my experience they break down and rust besides the fact that they are ugly and really boring to drive From my experience Cadillacs generally doesn’t need fancy special tools though sometimes a special tool can make the job easier.
  14. First of all, check the codes. Otherwise you are just throwing parts at it at your expense and time. Sometimes the codes don't manifest until after a couple of error cycles. If you still don't have codes then I would NOT suspect a clogged cat because they usually let you drive around at reduced rpms and makes the engine stumble at higher rpms. On the other hand your vintage of the STS (2001-2003 I believe) did have some problems with the crankshaft position sensors. They are quite easy to replace. You have to remove the oil filter adapter to reach them and the manual recommends that you replace the quick connect fittings to the oil lines if you have the engine oil cooler. But I insist that you check your codes again and drive around until you get a code before you start throwing parts at it. It can be a numerous count of things. For instance I had a broken wire next to the MAF-sensor that behaved the same way. No codes until I tried a couple more times. If you are really unlucky there will be no codes which is very unusual. Even an intermittent code like for my MAF-sensor problem will be thrown after a while. If I would bet I would bet on the crankshaft position sensors. The car could be driven at any rpm at any speed but just at above idle at take-off it would stall.

    I have never replaced one on a Cadillac. My wifes STS has almost 200k miles on it The FSM says you only need a pipe wrench placed on the rack next to the inner tie rod housing and obviously a wrench on the flats on the tie rod housing. This is for both magnasteer and "quiet valve" what ever that option means.
